Thanks to e-cigs, I have not had a real cigarette since NOVEMBER. I feel 1000000000% better all the time.
And that one in November, was half of a co-workers one half drunken night. Hadn't had a real one in about a month at that point. I felt like utter crepe the next day. Coughing up gross stuff, my hair smelled. Ugh. Never again.
I highly recommend using them to help you quit. There are appox. a million different kinds out there. My SO and I like the Fin brand. They always have coupons online, and they sell them at wall-mart and wall greens. We like them because they are small (not like some vapes) and are not crazy flavors. Menthol is the craziest you get. They literally can fit in your pocket, and if you lose one, they are not expensive. http://www.fincigs.com/
